In addition, the author also discusses the socio-political context of mathematical statistics in the late 19th and early 20th centuries. According to his […]

The statistical quality profession has a love/hate relationship with the Gaussian distribution. In SPC, it treats it like an embarrassing spouse. It uses the Gaussian distribution as the basis for all its control limits while claiming it doesn’t matter. In 2024, what role, if any, should this distribution play in the setting of action limits […]

Like spouses in murders, errors are always the prime suspect when measurements go awry. As soon Apollo 13 had a problem, a Mission Control engineer exclaimed, “It’s got to be the instrumentation!” It wasn’t the instrumentation.

Within the quality profession, a capable process is one with a high . In the field, it is not quite so simple. My colleague Joerg Muenzing recently shared concerns about the process capability indices: “Many manufacturers that I know struggle with incapable processes. Intellectually, people understand the concept of capability, but are unable to effectively […]

Data visualization is not just the art of presenting data to an audience. Upstream from this, you use visualizations in data cleaning to identify defective points, and in exploratory analysis, to identify patterns of interest. Then, you validate these patterns with a more formal analysis. Once confident that you have findings of value to communicate, […]
